I Application filed December 20,192.0. Serial No. 431,841.

To all tri/0m i? 'may conce/"fa:

Be it known that I. JOHN MATNLANTn a citizen of the United States, resi ding at Laporte, in the county of Laporte and State of i Indianaq have invented a certain new and Figure 2 is a vertical sectional elevation ol an oscillating bucket inI operative position; and

Figure 3 is a detail section on line 3 3 of Fig'. l. A is a grain elevator, the details of which form no `part of this invention and which are therefore not illustrated in detail, It

is provided with the hood B which has in its forward and downward end the `discharge l5 port (l through which grain adapted to be discharged into the bucket D. D is a partition within the bucket which divides it into equal parts. D2 D2 are Ainlet ports in the bucket through which grain or other material may be dumped. D3 D3 are discharge ports in the bottom of the bucket. D4t is a trip angle located adjacent the inlet ports and along one side ot the top ot the bucket. The bucket D is pivoted at D5 in the Y frame E which has the upper extension E and the two lower lateral extensions E2 E2. The uppeiI end of the extension E is pivoted at E3, in the scale beam .E which is pivoted at F on the part B and carries the weight F2 adjustahly mounted upon it. G is a member {ixed to the side ot the bucket D and having` the lateral extensions G G in each of which is mounted the downwardly depending arms G2 G2. I-I H are doors adapted to close the ports D3 D3, they are mounted .tor rotation atene end, respectively, one in each ot' the arms E2 E2 and adjacent their center they arc attached to the lower ends ot' 'the arms G2 G2 that is each of the doors H is pivot-ed at its outer edge on one of the arms E2 and adjacent its center it is pivoted on one of the arms G2. "Thus when the bucket oscillates and the member G moves, the arms G2 G2 are moved up and down with it and by this up and down movement one of llt) the doors H closed and the other is simultaneously opened. By means of this con struction when the bucket D is rotated with relation to the iframe E the doors H H are opened and closed automatically in response to such rotation. H. is a strip secured to the elevator A and to vone of the parts E2 and is adapted to steady the lbucket during its operation. I is a bracket mounted on the hood B, on which the roller bar Iis adjustably mounted. I2 is a roller mounted for rotationfin the lower end of the roller bar I andis adapted to be contacted by the trip angle D4. ,l is a counting mechanism adapted to count the oscillation ofthe bucket and'thus to register 'the material which is passed through the luicket The counting and supporting mechanism of the bucket has been described with ref erence to parts shown in Figure l. Ot course the tipping mechanism is re-produced on each side ot the bucket the scale beam is preferably made in the shape ot a yoke surlroundingr the upper end ot thev elevator.

The trip angle and trip roller bar may he used only on. one side of the mechanism although it is possible to havey a trip mechanism on each side ol the elevator.

Although I have shown in iny drawings an` operative mechanism, still it will be obvious that many changes both in forni, shape and arrangement of parts may be made without departingr from the spirit ot my invention, and I wish therefore, that my showing be considered as in a sense diagrammatic.

The use and operation of this invention are as follows:

The bucket is adapted to be used in connection with 4the controlled discharge of material where it is advisable to weigh such material as it is discharged. For this purpose the bucket is mounted on one end of the scale beam and is adapted to be discharged whenever the weight ot the contents ot the bucket has become sufficient to overbalance the scale beam.

When the bucket is in the position shown in Figure l the material is discharged from the elevator into the left hand portion of the bucket. When the material in this portion of the bucket is sulicient to depress the scale beam in opposition to the weight upon it the trip a gle disengages the roller whichis at the lower end of the roller bar and the bucket is then Yl'ree to rot-ale and because it is unevenly loaded it rotates to the lett into the position shown in Fig. Q. As this rotation takes place, the rate o'l`v the filled section ol the bucket is automatically opened and discharge commences, at the same tinie the gate of the empt7 compartment is autoniatically closed and material is discliarged from the elevator' into that part ot the bucket. TNhen su'liicient grain has been discharged from the loaded side of the bucket. the rveieht again arises and the beam at the opposite end of the trip ang-le comes in contact with the trip roller and remains in that relation until the Weight ot `grain on the right hand side of the bucket has become sullicient to depress the bucket and then that compartnient is dumped* The leitt side ot the bucket will be entirely,7 empty before the right side is su'lliciently loaded to tip the bucket again. This operation takes place repeatedlyY and aiitoinaticalljT as long` as material in suflicient quantities is 'fed into the bucket.

1. In an automatic grain scale, an elevator, a scale beam, and a bucket supported iai-cigares Afrom said beam and adapted to rise and ilall therewith and mounted lior oscillation about a pivot point, a rigid means 'l'or preventing said oscillation when said bucket is raised, said means beingl :in vertical alignment with the pivot point oli said bucket.

2, In an automatic grain scale, an elevator, a scale beam, and a bucket supported from said beam and adapted Ato rise and tall therewith and mounted for oscillation about a pivot point, a rigid means for preventing said oscillation when said bucket is raised, said means beingin vertical alignment with the pivot point of said bucket, said bucket provided with central interior partition, a pair oit bottom openings one on either si-:le oli said partition, and a pair oit hinged gates one for each ot said openings, said gates adapted to be opened alternately by the oscillation ot' said bucket, and means secured to the side oit said bucket tor operatingT said gates.
